Title: Improvements in or relating to fastener assorting apparatus
IPC: B07C5/12
Filed: 1949-07-28
Abstract: 665,035. Nailing, BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). July 27, 1950 [July 28, 1949], No. 19821/49. Class 89 (iii). In an apparatus for supplying fasteners (e.g. nails) to a machine for attaching heels to shoes which includes a rotary nail drum 54 and an oscillating nail carrier 44 comprising raceways 46 and nailways 48, the nail carrier is mounted on springs 38, 40 for movement lengthwise of the raceways and nailways. Vibration of the carrier 44 is effected by a compound eccentric 318, Fig. 12, on a shaft 538, 550 driven by a belt 138 and pulley 534 from a continuously driven shaft 72. An eccentric 564 is mounted on eccentric portions 542, 548 of the shaft 538, and counterweights 560 are mounted on opposed eccentric portions 556, 558. The eccentric 564 operates a connecting rod 574 to which is fixed an inertia device 576 which is secured to leaf springs 580 fixed at their upper ends to the carrier 44. Adjustment of the various eccentric portions and the counterweights is effected by a rod 592. The nails pass from the main portions 316 of the raceways 46 through an adjustable gap 390 which ensures that they will slide head first down arcuate portions 382 to the nailways 48 and thence to an inverter roll 134 and by passages 204 (not shown) to the loader block of a heel-attaching machine. Oscillating cleaver prongs 326, 370 (not shown), are provided between adjacent raceways or nailways to knock transversely-lying nails into the raceways or nailways, or through the spaces therebetween for return to the drum 54. For short nails, a known oscillating roll 134 is employed, but for longer nails a rotary roll is provided having diametrical holes 670, Fig. 20A, or pairs of holes 630, Fig. 20, offset from the axis of the roll, successive holes or pairs of holes being in directions at right angles to one another. An adjustable spring-pressed stop 464 is provided beyond the roll 134. The nail drum 54 is supported on sleeves 174 coupled together by a belt 170 and driven at either of two speeds through gears 158, 160, operated by one of a pair of gears 148, 150 which are slidable, by means of a yoke 152, on a shaft 144 driven by a worm 140 and gear 142 from the continuously driven shaft 72. The shaft 144 carries a cam 186 which houses a one-revolution clutch controlled by the heelattaching machine. The cam 186 has a serrated front face 194 which is engaged by a cam roll 196 (not shown) to vibrate the inverter roll 134 about its axis, and a groove 198 in its rear face to receive a roll 200 on a lever 202 secured to a yoke 116 to render the shaker shaft assembly 136 ineffective, while the inverter roll 134 is operated by opening a divided pulley on shaft 72. The inverter roll 134 is operated by the cam roll 196 (not shown) through suitable mechanism. Where less nails are required in a batch, the nailways may communicate in pairs with a single passage 204 (not shown) and a further fastenersupplying apparatus may be driven from a further divided pulley on shaft 72.

Abstract: 737,226. Filing papers. SHANNON, Ltd. July 20, 1954 [July 20, 1953], No. 20076/53. Class 146(1). A frame comprising horizontal rails for the suspension of stiffening bars at the upper edges of folders and including vertical posts connected by cross bars, the whole to be inserted in a filing drawer or cabinet, has each rail at one end passed through and held frictionally by a slot bounded by part of a cross bar and part of a corner post and a hand-operated locking member, constituted by a strip which lies along the cross bar in a locking position, acts by lever or wedge action to urge the cross bar downwards to grip the rail. As shown in Figs. 1 and. 3, the frame comprises rails 1, cross bars 2 and corner posts 3 joined by bottom bars 25 all of uniform flat strip metal. Each corner post 3 is cranked to form a shoulder 4 an offset vertical part 5, a shoulder 6 and vertical upper end part 7 cut away to form a narrow neck 9 surmounted by a head 10 wider than the neck but narrower than the strip 3. Each cross bar 2 has at each end a down turned end 11 terminating in a tongue 12 and has a hole through which the head 10 may pass, the tongue 12 then entering a hole 8 in the shoulder 6, leaving a slot between the parts 7 and 11 through which the end of a rail 1 may be passed. The locking member 13, comprising a strip of metal, has two slots 14, 15, the slot 14 being long enough to pass over head 10 when at right angles to the bar 2 and wider than neck 9, the slot 15, in the locking position, lying under a hook 17 made by slotting the bar 2. In the locking position, the member 13 bears on a projection 16 on the bar 2 adjacent the hole for neck 9 to press the bar downwards to grip the rail 1. In a modification to narrow the width of the frame, the tongue 12 is cranked inwardly and the shoulder 6 narrowed in width. As shown in Fig. 7, the corner posts 3 and cross bars 2 are substantially the same, with no tongue 12 and hole 8, but the locking member 18 acts with a wedging action and comprises a strip with an elongated hole 19 to receive the neck 9 of the corner post 3 and allow movement in the direction of length of the strip. An inclined part 20 is formed outwardly of the hole 19 so that as the strip 18 is pressed inwardly, the part 20 rides up over the bend 22 between the bar 2 and its end 11 so that the bar 22 is pressed downwardly to grip the rail 1. Inward movement of the locking strip 18 is guided by a nose 23 thereon riding in a slot 24 in the cross bar 2. Specification 557,532 is referred to.

Filed: 1924-08-26
Abstract: 241,662. English Electric Co., Ltd., and Bremner, F. D. H. Aug. 26, 1924. Controllers with no-volt release: master control systems.-In an electric motor control system, in which a master switch 8 effects circuit conditions to cause an auxiliary electric or pneumatic motor to drive a secondary switch 7, the movement of which cancels the said circuit conditions, a novolt relay coil 3 is provided in the main motor circuit or in shunt to a part thereof so as to be traversed by a current proportional to the motor current. Movement of the switch 8 to its first position completes a circuit through a hand reversing switch 13, a reverse 14, line breaker coils 4, segment 15 of switch 7 to earth, the line breakers close thereupon completing the main motor circuit through relay 3, which closes its switches 1, 2, and the line breakers move associated contacts 5, 6 to complete a shunt circuit for their coils 4 to earth. Associated contact 12 completes the circuit of a relay 16 to earth through switch 2 and segment 21 on switch 7. Armature 20 is thereby attracted and completes the circuit of the auxiliary motor so that notching-up can start. Upon voltage failure in the main motor circuit, switches 1, 2 open, interrupting the circuit of coils 4 so that the line breakers open and associated contacts drop. Circuit of relay 16 is now completed through contact 18 and segment 19 and the auxiliary motor returns switch 7 to its initial positon, whereupon the coils 4 areagain energized and the line breakers close, but the circuit of the coil 16 is still open at the switch 2, so that notching-up cannot start until the main motor current again flows and the relay 3 is energized.

Title: Radio antenna system and associated thermionic valve generator
IPC: H03B5/18
Filed: 1944-10-20
Abstract: 585,746. Valve generating circuits; aerials. STANDARD TELEPHONES & CABLES, Ltd. Oct. 20, 1944, No. 20346. Convention date, Jan. 5. [Class 40 (v)] In a combined oscillator and rhombic aerial system, a feed-back circuit between the anodecathode and grid-cathode circuits of the valve includes the conductors of the rhombic. The oscillator valve 1, tuned by inductance 9 and condenser 10, feeds over a coupling coil and transmission line 13 the rhombic aerial 14. The remote end feeds through the transmission line 15 and artificial line 15<1> a coil 21 coupled to the cathode isolating coils 24, 25 to maintain the circuit in oscillation. The main tuning control is variable condenser 10, the adjustment of the artificial line 15<1> giving a fine control. The grid of valve 1 is held effectively at earth potential by the condenser 8. When employed as a jamming transmitter, contact arm 30 is rotated in synchronism with condenser 10 and the coupling of the coils comprising the artificial line 15'. By this means, all frequencies in the band are radiated, except those corresponding to the position of condenser 10 when arm 30 is in the gap between contacts 31, the breaking of the cathode circuit causing valve 1 to cease oscillating. The frequency of oscillation may also be adjusted by changing the lengths of the transmission lines, or by coupling a tuned circuit to one of the lines or by inserting a dielectric between the conductors comprising the line. The resonant anode circuit may consist of a short-circuited line, the transmission line 13' being coupled by condensers. In a modification, Fig. 2 (not shown), valve 1 is connected in a neutralized circuit. In a further modification, Fig. 5 (not shown), the valve 1 operates as a power amplifier stage, driven by a crystal-controlled oscillator, the feed-back being insufficient for self-oscillation.

In the example -the rubber rings 8, 9 are of frusto-conical form and of axial width much greater than their radial thicknesses, which are in inverse proportion to the diameters of the rings. The outer edges of the rings are vulcanized to discs 2 which are bolted to the outer faces of the hub, the inner edges being vulcanized to discs 13 which are bolted to supporting discs 4 and 5 located on opposite sides of the annular guide plate 6 and each detachably bolted to the inside of the rim 3. The guide plate 6, which may be either connected to the hub 1 or machined from it, is provided on its outer surface with a cover 6a of a material having frictional properties that allow it to slide easily upon and relative to the discs 4 and 5. The cover 6a may be a surface layer on opposite sides of the annular guide 6, or a separate part fitted and secured to it as shown. A resilient ring 12 may be provided around the periphery of the guide 6 to act as an end stop. Cooling ribs 11 are provided on the brake drum.
